Duodenal and biliary atresia associated with facial, thyroid and auditory apparatus abnormalities: a new mandibulofacial dysostosis syndrome?

Abstract

We report a female child born at 36 weeks of gestation with multiple abnormalities including dysmorphic and coarse facial features with features of mandibulofacial dysostosis that include bilateral microtia with the absence of external auditory meati and Mondini dysplasia as well as, duodenal atresia, intestinal malrotation, anterior displacement of the anus, left hemiaplasia of the thyroid and biliary atresia in sibs. The associations of duodenal atresia with intrahepatic and extrahepatic biliary atresia in sibs have been reported, suggesting an autosomal recessive syndrome. However, the associated external, middle and internal ear anomalies and the thyroid malformation, however, have not been reported in this condition. To the best of our knowledge, this is a hitherto new syndrome with an unknown inheritance.
